Different types of technology and wireless networks allow devices to talk (send data) to each other and to the web (TCP / IP networks) wirelessly. There are a number of different wireless technologies out there that can be implemented in hardware products for the Internet of Things (IoT) and Machine to Machine (M2M) communications. Both of these are available on Aruba Wireless.
The Institute of Electrical and Electronics Engineers (IEEE) has seven task groups for 802.15 technology. These groups set standards for the general types of wireless technology used for private area networks. The 802.15 task group includes: WPAN / Bluetooth, Coexistence, High Level WPAN, Low Level WPAN, Mesh Networks, Body Area Networks, and Visible Light Communication. Each IEEE protocol has its own advantages and limitations. Promising developments expand their applications and potential uses.

IEEE 802.15.4: ZigBee
A wireless technology that is currently gaining traction in the LPWAN group, ZigBee is an open global standard and is specifically designed for use in M2M networks. This technology is inexpensive to run and does not require much power, making it the ideal solution for many industrial applications. This technology has low latency, and a low duty cycle, allowing the product to maximize battery life.
The ZigBee protocol offers 128-bit AES encryption. This technology is also used in Indonesia. Mesh network, which allows nodes to be linked together through several paths. Wireless technology is expected to eventually be implemented in things like smart home devices. The technological ability to connect multiple devices simultaneously makes it ideal for the home environment. You can get this technology by relying on Aruba wireless.
IEEE 802.11: WiFi
WiFi uses radio waves (RF) to allow two devices to communicate with each other. This technology is most often used to connect internet routers to devices such as computers, tablets and telephones; However, this can be used to link together two hardware components. WiFi is a local wireless network that runs the 802.11 standard set by the Institute of Electrical and Electronics Engineers (IEEE).
WiFi can utilize the 2.4GHz UHF and 5GHz SHF ISM global radio band.
IEEE 802.15.1: Bluetooth and BLE
Bluetooth and Bluetooth Low Energy (BLE) are wireless technologies that are applied to transfer data over short distances. This technology is often applied to devices that take into account small devices connected to the user’s cellphones and tablets. For example, this technology is applied in many speaker methods.
Bluetooth Low Energy applies less power than standard Bluetooth and is applied in hardware such as fitness trackers, skilled watches, and other connected devices to transmit data wirelessly without much disruption to battery power on the user’s cellular phone.

Aruba Wireless Does 2.4 GHz Spectrum Exist Back?
When most people think of the 2.4 GHz spectrum we definitely think of older, older devices. The reality is that many various devices are still using this 2.4 GHz wireless network band.
From smart phone devices to IoT to some new digital devices that don’t use the 5GHz spectrum. This could start to cause problems because the newer wave of Aruba Wireless WiFi technology has focused on the 5 GHz spectrum – until now.
The truth is that 2.4 GHz never disappears no matter how hard some of us try to make it happen. I recently bought a new wireless home security system with an IP camera from a major provider and only 2.4 GHz is compatible.
I like to think that 2, 4 GHz makes a comeback because of the new work that 802.11ax is trying for wireless networks in totality. Unlike 802.11ac, the new Aruba Wireless WiFi 6 wireless technology wants to operate on the 2, 4 GHz and 5 GHz bands.
Right now, I want to say that speed is going to vary depending on the band, but there are some alibis that mean that 802.11ax wants to increase the 2.4 GHz spectrum. The main subject that I want to focus on is total network capacity. Like that which really makes me excited about maybe the future of 802.11ax. This is intended to support and provide better connectivity to more features than before.
For the matter of the 2.4 GHz capacity it is king when it comes to current networks. With more and more devices being exchanged for “smart” devices, usable technologies and other general computing products, networks need to handle this large wave of devices more than ever before. There are several 802.11ax features that will help handle the capacity of this larger device.
The beginning is the target wake time (TWT). I’m saying that many of the 2.4 GHz features are going to be IoT features. This feature is not required to report and use wireless as long as possible. By using TWT, this feature can make the network adapter sleep for a certain period of time, thereby reducing the number of active features on the saturated 2.4 GHz band.
